The TDK Life on Record CD Lens Cleaner helps maintain optimal hardware performance. Dust and everyday handling of CDs can create buildup on the side of the discs where data is stored. This buildup can transfer from the discs to the recorder or player's optical laser lens, causing data errors, skipping and other problems. The TDK CD Lens Cleaner helps eliminate buildup, while maintaining optimal performance and maximizing your home entertainment investment. Simple audio instructions make it easy to use. It also works with DVD players, CD/DVD computer drives and game consoles.
